Adenomatous and serrated polyposis syndromes

Conventional adenomas and serrated polyps are the most common neoplastic precursors of colorectal cancer and may occur in a sporadic or syndromic setting. Adenomas are subclassified into tubular, tubulovillous and villous while serrated polyps occur in three distinct histological forms: hyperplastic polyp, sessile serrated polyp and traditional serrated adenoma. In patient's undergoing routine screening or diagnostic colonoscopy, single or multiple histological types of colorectal polyps may be present concurrently in variable numbers.
